That would be
1] 2000 meters every 1000 seconds (2 km)
1400 / 2 = 700 sets of 1000 seconds
1000 x 700 = 700000 seconds
700000
-604800 s in a week
------
106200
1.175 weeks
2] 6 hrs rest each night
18 hrs walking
3600 seconds/hour
x 18
----
28800
+36000
------
64800 seconds per day
700000/64800 seconds for the entire trip.
10.802 days for the entire trip.
THERE YOU GO

If you walk 2m/sec then to walk 1km will take you
(1000m)/ 2m/sec=500sec.
To go 1400 km will take you (1400)(500) sec or
700,000sec. An hour is sixty minutes and a minute is 60 seconds, so there are (60)(60)=3600 seconds in an hour.
The whole trip in hours will be 700,000/3600 hrs or
194.44 hrs.
If you stop between 10 pm and 8am then you will be traveling 14 hours a day.
To travel the needed 194.44 hours will take you
194.44hrs/ (14 hrs/day)=just under 14 days.

1) 1400*1000/2 = 700,000 seconds = 8 days, 2 hours, 26 minutes, 40 seconds (194h, 26m, 40s)
2) 13 days, 12 hours, 26 minutes, 40 seconds

answer to Q1)
1400 kilo meters = 1400000 meters.
speed = distance / time
time = distance / speed
SO time = 1400000 / 2
= 700000 seconds
time it would take to walk from land's end to jhon o'groats
= 700000 seconds which is equal to 194.44 hours..
GOOD >?

1]dist=1400 kilometers;
speed=2met/sec=7200met/hr=7.2km/hr
time in hrs=1400/7.2=194.4 hrs
2]10 hrs rest; 14 hrs walk
time=194.4/14=13.88 days
=13days and 21 hrs
He will reach there on the 14th day
in the evening around 10 pm
